Calcium channel blockers increase the risk of aortic aneurysm and dissection.

ABSTRACT: Aortic aneurysm and dissection (AAD) are life-threatening conditions without effective medications. Impaired contractility of vascular smooth muscle cells (VSMCs) is strongly linked to AAD, but the role of calcium channel blockers (CCBs), which directly inhibits VSMC contractility, in AAD remains unclear. Here we showed data from 501,878 initially AAD-free participants in UK Biobank. Over a median follow-up of 13.5 years, CCB users had higher AAD risk (HR = 1.31) than hypertensive patients not receiving antihypertensive treatment. In mouse models of AAD, CCBs significantly aggravated aortic stiffness and AAD development. For patients with type B aortic dissection who underwent endovascular repair, CCBs limited AAD regression compared with other antihypertensives. Moreover, silencing of pro
